二维的

First, face image is decomposed by two dimension wavelet transform. Then the low frequency subband is convolved with Gabor filters and downsampled by a factor. After that, the kernel principal component analysis is used to reduce the dimension of Gabor features. Finally, minimum distance classifier is used to classify.

它现在被重新画了一遍，作为某种以二维形式出现、但具有成为三维存在的潜力的东西重新出现。

Compared with 2D GIS space data model, the 3D model can be divided to four types that are tessellating model, vector model, hybrid model and analytical model.

与二维GIS空间数据模型类比，三维模型又可划分成基于镶嵌的数据模型、基于矢量的数据模型、混合型数据模型和分析型数据模型四种类型。

We demonstrate our approach by constructing a full cart animation from dog, cat, snake and human animations as well as applying a 2D video of the wheel of a car onto the wheels of the cart. Other examples produced from our prototype system are also given in the paper to illustrate the generality and robustness of our approach.

本文通过从狗、猫、蛇、人体的三维动画与二维车轮视频来产生复杂的马车动画来阐明该方法，另外原型系统还产生其他几个例子来进一步验证其通用性和鲁棒性。

On this basis, using the same theories and methods, we set up the three-dimensional steady-state models of ideal well productivity about a reverse double-branch horizontal wells, the three branches of radial horizontal wells, fish-bone shape three branches horizontal wells and two-dimensional four branches horizontal wells In five reservoirs respectively.

在此基础之上，运用同样的理论和方法，建立了反向双分支水平井、辐射状三分支水平井、鱼骨形三分支水平井和二维四分支水平井这四种分支水平井分别在以上五种油藏中的三维稳态理想井产能模型。

So the structure is designed to ensure reliable mould, working with other components., Based on 3d drawing die assembly drawing and 2d.

Owing to the multi-analysis solution problems, the method using aircraft upright empennage direction to simplify multi-analysis solution is presented for the first time.

针对二维图象中三维信息提取的多值解问题，首次提出了利用飞机垂直尾翼方向进行多值解简化的方法。

Based on the two face images of the same person at front and half-profile view and an MPEG4 3D generic face model, we estimate the poses of the face at these two images and establish their 2D mesh models. Multiple views of the same face can be synthesized by image interpolation and warping, meanwhile occlusion problems are solved reasonably.

基于同一人脸的正面和半侧面图像，引入三维通用人脸模型估计其初始朝向，分别建立两图像的二维网格模型；然后采用图像插值和变形技术合成不同朝向人脸，并合理地解决遮挡问题。

Doppler weather radar is one of the most powerful tools for investigating severe mesoscale and microscale weather systems.

多普勒天气雷达是研究中小尺度天气系统的重要工具，但却只能提供风场的径向速度，因而必须通过风场反演技术来求解二维或三维风场。

But we don't care about Battlegrounds.
